OTTO G. J. KOCH, OF BELVIDERE, ILLINOIS.

STRING MUSICAL INSTRUMENT.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed November 7, 1907. Serial No. 401,094.

To all whom it may concern:

Be it known that I, OTTO G. J. Koon, a citizen of the United States,residing at Belvidere, in the county of Boone and State of Illinois,have invented certain new and useful Improvements in String MusicalInstruments, of which the following is a specification.

The object of this invention is to construct a musical instrument of theviolin variety, in which the body is formed with convolutes terminatingin an opening extending approximately the length'of the instrument.

In the accompanying drawings, Figure 1 is a perspective view of myimproved. musical instrument. Fig. 2 is a lengthwise section on dottedline a a Fig. 4, looking in the direction of the arrow 0. Fig. 3 is alengthwise section on dotted line a a Fig. 4 looking in the direction ofthe arrow (1. Fig. 4 is a transverse section on dotted line b 6 Figs. 2and 3. Fig. 5 is an elevation of the end block as seen from itsinnerface and showing the groove for the end of the scroll. Fig. 6 is anelevation of the head block as seen from its innerface, and showing thegroove for the end of the scroll.

The head block 1 hasits inner face formed with a scroll groove 2 inconvolute form, and the outer surface of this head block conformsapproximately to the form of the scroll groove. The end block 3 has itsinnerface formed with a scroll groove 4 in convolute form, and the outersurface of this end block conforms approximately to the form of thescroll groove.

A scroll 5 has its ends seated in the scroll grooves 2 and 4, andsecured to the outer surface of the head block 1 and end block 3. Thisscroll is of larger diameter at about the center of its length than atits ends, in order to increase the area. The scroll is somewhatflattened and the flattened portions 6, 7, 8

and 9 are thicker than the ends of the scroll as shown at Fig. 4. Theflattened portions are thicker in the center of their length for somedistance therefrom, and taper to their ends as shown in Figs. 2 and 3.

As shown in Figs. 1 and 4 the outer edge 10 of the scroll is separatedsome distance from the next adjacent section of the scroll, therebyleaving a space or opening 11, through which the sound escapes.

A post 12 is located between the sections 6 and 7. A post 13 is locatedbetween the sections 7 and 8, and a post 14 is located between thesections 8 and 9. These posts serve to hold the sections fromcollapsing. Along the innerface of the section 6 is secured a bar 15thicker at its center and tapering toward its ends. A block 16 rests incontact with the underface of the bar 15 and the top face of theflattened section 7.

To the underface of the flattened section 7 is secured a bar 17, thickerat its center and tapering towardits ends. These bars serve to stiffenthe flattened sections 6 and 7 of the scroll.

The head block 1 supports the neck 18 and finger board 19. The saddle 20is connected to the end block 3. The end peg 21 has a connection withthe end block. The tail piece 22 has its usual connection with the endpeg. The bridge 23 is located between the finger-board and the tailpiece, and adjacent to the posts 12. The strings 24 have the usualconnection with the neck and tail piece.

The bars 15 and 17 underlie the E and A strings. By this construction ofmusical instrument, the different convolutes forming the scroll,increase the sounding board area, thereby increasing the volume of thesound, and by forming the opening 11 the length of the distance betweenthe head block -1 and end block 3, the sound has a greater opportunityto escape.

Brackets 25 are located between the rounded portions of two of theconvolutes. Brackets 26 are located between the inner edge of the innerconvolute and the rounded end of the adjacent convolute, and brackets 27are located between the .outer edge 10 and the rounded portion of theadjacent convolute. These brackets hold the convolutes properlyseparated.

I claim as my invention.

1. A string musical instrument comprising a head block, an end-block,and a scrollshaped sounding-board connecting the head and end-blocks.

2. A string musical instrument comprising a head-block, an end-block,and a scrollshaped sounding-board connecting the head and end-blocks andsaid instrument provided with an opening extending approximately thedistance between the blocks.

3. A string musical instrument comprising a head-block, an end-block,and a scrollshaped sounding board connecting the head and end-blocks,the front and back portions of the sounding-board being thicker in themiddle than at the ends.

4. A string musical instrument comprising :1. head-block, an end-block,a scroll-shaped sounding-board connecting the head and end. blocks, andposts holding the turns of the sounding-board separated.

A string musical instrument comprising a heed-block, and end-block, ascroll-shaped sounding board. connecting the head and. endblocks, andreinforcing bars secured to the undcrfztce of two of the turns of thesoui'uling board.

6. A string musical instrument comprising a lIQitLl-blOCli, andend-block, a scroll-shaped sounding board connecting the head and end- Iblocks, reinforcing bars secured to the underface of two of the turns ofthe sounding board, and a block located between one of the bars and. theWall of a turn.

7. A string musical instrument comprising a, head-block, a scroll-shapedsounding board connecting the head and end-blocks, and brackets holdingthe sevcrnl turns of the sounding board separated.

In testimony whereof I have hereunto sci my hand in presence of twosubscribing \vitnesscs.
